The intracellular antioxidant copper, zinc-superoxide dismutase (Cu,Zn-SOD) was immunohistochemically studied in the kidney of rats under fasting stress condition. A total of 45 male Wistar rats were used for this experiment. They were divided into three groups; control group, 3 days fasted and 5 days fasted stress groups. The Cu,Zn-SOD was observed qualitatively in the kidney tissues especiall...

The interplay between nitric oxide and superoxide to form peroxynitrite is a major biological process that competes in a remarkably subtle fashion with superoxide dismutase in vivo. The complex interactions between superoxide, nitric oxide reveals some extraordinary features about the difficulties of effectively scavenging of superoxide in a biological system. The discovery of dominant mutation...

The entire cDNA sequences were determined by reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE) techniques for equine copper/zinc superoxide dismutase (Cu/Zn-SOD) and manganese superoxide dismutase (Mn-SOD) through the use of total RNA extracted from the testis of an adult Thoroughbred. The results revealed a protein coding region for equine Cu/...
